Meiosis

  1. Meiosis I is also called __?__.
    Reduction Division
  2. Meiosis II is also called __?__.
    Equational Division
  3. In terms of human cells that enter meiosis I: how many chromosomes do these cells have?
    46
  4. In terms of human cells that enter meiosis I: are the chromosomes of these cells duplicated or unduplicated?
    Duplicated
  5. In terms of human cells that have completed meiosis I (but have not yet entered meiosis II): how many chromosomes do these cells have?
    23
  6. In terms of human cells that have completed meiosis I (but have not yet entered meiosis II): are the chromosomes of these cells duplicated or unduplicated?
    Duplicated
  7. In terms of human cells that have completed meiosis II: how many chromosomes do these cells have?
    23
  8. In terms of human cells that have completed meiosis II: are the chromosomes of these cells duplicated or unduplicated?
    Unduplicated
  9. What is the short phase between meiosis I and meiosis II called?
    Interkenesis
  10. Are cells that enter meiosis I diploid or haploid?
    Diploid
  11. Are cells that enter meiosis II diploid or haploid?
    Haploid
  12. Are cells that complete meiosis II diploid or haploid?
    Haploid
  13. What happens during interphase before meiosis I?
    DNA replication
  14. What word means "pairing of homologous chromosomes"?
    Synapsis
  15. What are homologous chromosomes?
    Same genes carried on each chromosome (ex: eye color).
  16. Why does crossing over occur?
    So there can be an exchange of genetic material leading to genetic diversity (variation).
  17. How many chromosomes does a human lymphocyte have?
    46
  18. How many chromosomes does a human gamete have?
    23
  19. In what phase of meiosis does crossing over occur? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Prophase I
  20. In what phase of meiosis does pairing of homologous chromosomes occur? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Prophase I
  21. In what phase of meiosis do sister chromatids split and are pulled toward opposite poles of the cell? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Anaphase II
  22. In what phase of meiosis does the cell invaginates to form 2 haploid cells with duplicated chromosomes? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Telophase (and Cytokenesis) I
  23. In what phase of meiosis does the cell invaginates to form 2 haploid cells with unduplicated chromosomes? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Telophase (and Cytokenesis) II
  24. In what phase of meiosis do homologous chromosomes line up in pairs along the center of the spindle? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Metaphase I
  25. In what phase of meiosis does a haploid number of chromosomes first becomes visible? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Telophase I
  26. In what phase of meiosis does the spindle form in a cell with a diploid number of chromosomes? (Remember to put I or II after the name of the phase to indicate meiosis I or meiosis II.)
    Prophase I
